Just tidying up a few things.

Incidentally, as Mr Molluscan keeps asking me why I think I'm better than Popper, Newton and Einstein, perhaps I should ask him now whether he thinks he's better than Professor Dawkins, who, er, knows a fair bit more about evolutionary biology

Steve, you have said that you cannot excuse Newton for his work on alchemy despite the fact that that was mainstream thinking at the time. You have argued on another thread that Popper was wrong. The comment about Einstein was a joke and might better be directed at Musket (see below). As far as I can recall, I have never commented on Dawkins' abilities as an evolutionary biologist. I am sure he is brilliant. Do you take my disagreements with you faith based attitude to evolution as criticism of Dawkins?

In my researches, I came across this article by Stephen Jay Gould http://www.stephenjaygould.org/ctrl/gould_fact-and-theory.html. In it he says "Einstein's theory of gravitation replaced Newton's". Dozy sod.
